This is only a partial list, I am sure.
Also,
I can only list places I have actually purchased parts from.
Since
I live in the USA, that sort of explains the bias towards US based
suppliers.
If you know of a supplier for various parts listed, send me an e-mail
and
I will add it. Also, if you think other parts should be added to
this list, send me email. Hopefully, all will find this list
useful.
